The stunned Pakistanis, members of the Mekaal Hasan Band, as well as the organisers were pushed into a corner. But no one was injured and there was no damage to property, a Press Club official said.

Police rounded up several Shiv Sainiks and detained them.

Justifying their action, Shiv Sena spokesperson Rahul Narvekar said it was the party's policy not to allow any Pakistani artiste to perform in Mumbai.

"They behead our soldiers on the border, indulge in terror activities and then come here to make money. We shall not tolerate this," he said.

Gurbir Singh, president of the Press Club Mumbai, said he has spoken to Maharashtra Home Minister R.R. Patil and police officers seeking additional forces at the venue.

"This is the first initiative of its kind and aims to create a positive interaction between musicians of India and Pakistan, create a relationship of mutual benefit, trust and thereby strengthen peaceful ties between the two countries," said organiser Jatin Desai.
